Bulk forming technology of sandwich coil insert
Votavová, Jitka ; Dohnal, Ivo (referee) ; Forejt, Milan (advisor)
VOTAVOVÁ Jitka: Bulk forming technology of sandwich coil insert. The project elaborated in frame of engineering studies branch M-STG. The project is submitting design of technology production of the sandwich coil insert - from aluminium alloys AlMn1 ČSN 424432. Production sequence was proposed upon linear analyse of bulk forming especially to extrusion and upsetting. Technological calculations were made. Maschine was select automatic transfer press TPM8, nominal power 1 000 kN (producer SMERAL Brno). Extruder will make from tool steel 19 436.8, clamp ring from tool steels 19 436.8 and extrusion die from tool steel 19 436.8. Heat-treatment extruder and clamp ring according to drawing.

Forming technology production of ending of brake hose
Obůrka, Miloš ; Šlais, Miroslav (referee) ; Forejt, Milan (advisor)
The purpose of the diploma thesis elaborated during studies of Engineering technology is to project the technological process for production of brake hose end made of 12010.3 steel by cold forming. Based on the study of the cold forming problems and following technical calculations of the production process was designed a 3 steps process of forming. As a semiproduct was chosen wire stub with a diameter of 11.2 mm and a length of 27mm. The production is designed for automatic multistage press TPZK 25 from local manufacturers Šmeral Brno, a.s.

Metal forming production of bush by cold extrusion.
Šimeček, Tomáš ; Šlais, Miroslav (referee) ; Forejt, Milan (advisor)
ŠIMEČEK Tomáš: Metal forming production of bush by cold extrusion. The project elaborated in frame of bachelor study degree brings a proposal of step by step metal forming production of bush by cold extrusion. Workpiece is made of normalized circle-shaped bar using 12 050 steel. The step by step production is based on literary pursuit of volumetric forming and calculation and is designed into five steps containing cutting, pressing and extrusion. These operations will be done on multistage pressing automatic machine TPZK 25 manufactured by ŠMERAL Brno, plc. with nominal pressing force of 5MN. Semi-finished product is placed into tooling´s workspace with manipulator. Final part extraction is solved with ejector integrated in automatic machine. Tools are made of tool steel, extrusion punch is designed of 19 550.4 steel, extrusion die is designed of 19 436.4 steel and extrusion die´s band is designed of 19 733.4 steel. Tools are designed to be improved by hardening and drawing.
